To remove one electron from singly ionized helium, will require approximately 54.4 eV or 8.72 1020 J of energy.
The amount of energy required by an isolated, gaseous molecule in the electronic state of the ground to absorb in order to discharge an electron and produce a cation has been known as the ionization energy. The amount of energy required for every atom in a mole to drop one electron is most often given as kJ/mol.
Anything that causes electrically neutral atoms and molecules to gain or lose electrons in order to become electrically charged atoms as well as molecules .
Therefore, the "To remove one electron from singly ionized helium, will require approximately 54.4 eV or 8.72 1020 J of energy."

Because they insulate either the heat or the coolness within the food item. But keep in mind- when it comes to electricity aluminum isn’t an insulator.
Non metals tend to form covalent bond
Equation is as follow,
<span> SnCl</span>₂ <span> + PbCl</span>₄<span> </span>→ <span>SnCl</span>₄ <span> + PbCl</span>₂
Oxidation State of Sn on left hand side in SnCl₂ is +2, while that in SnCl₄ on right hand side is +4. Means Sn has lost two electrons. Hence, it is oxidized and has worked as a reducing agent (has reduced Pb from Pb⁺⁴ to Pb⁺²).
Oxidation State of Pb on left hand side in PbCl₄ is +4, while that in PbCl₂ on right hand side is +2. Means Pb has gained two electrons. Hence, it is reduced and has worked as an oxidizing agent (has oxidized Sn from Sn⁺² to Sn⁺⁴).
